Bitters

Just went to a California raley’s to buy some coffee and bitters (18years old). When I got to the counter the lady asked for my ID, I asked her why, and she said the bitters were alcoholic. I said they’re technically non alcoholic and I’m just getting them for my coffee but she refused to sell to me. I just think it’s crazy how I can own firearms (which I do), sign my life to the military, get married and live alone but god forbid a man puts a dash of orange bitters in his coffee.
